Foundation fieldbus : from theory to practice

This paper describes the main characteristics of the Foundation Fieldbus (FF) technology considering both communication levels, namely H1 and H2, which have bit rates of 31.25 K and 100 Mbit/s, respectively. Several details about the physical layer, communication stack and user layer will be highlighted. Topics related with the configuration of instruments, as well as the design and implementation of supervision software, based on a LabVIEW interface, will be presented. A pilot plant that includes temperature, pressure, level and flow variables will be used to test and validate the capabilities of FF systems. Experimental results will be analyzed, their meaning discussed and the overall performance evaluated

WinCC, profibus and profinet systems for teaching purposes

This thesis project is a continuation of multiple projects that first began in 2011. In 2011, Murdoch University procured the following new technologies to introduce into the Industrial Computer Systems Engineering (ICSE) major under their Bachelor of Engineering Honours undergraduate degree: • two industrial networking standards (Profibus and Profinet), • remote network monitoring or supervisory control and data acquisition (SCADA) control software (SIMATIC WinCC) and, • variable speed drives Before these technologies could be taught, they first had to be learnt and understood. To achieve this, since 2011, students have been working with these technologies and producing learning materials to assist future students. The primary objectives of this phase were to: i) Research, assemble, review and simplify existing project materials and, ii) Design and create learning modules which encapsulate the existing project materials in the form of ‘Lab guides’ to be used in the ICSE Laboratory Room. These materials will be used in the ENG448 SCADA and Systems Architecture Unit commencing in Semester One of 2017. These primary objectives were achieved, with the actual learning modules delivered to the project supervisor electronically. This report begins by introducing readers to the background of the project, its motivation and objectives for this phase in sections one and two. Readers are then informed about the various new technologies that will be taught in the learning modules in section three and then outlined as to the approach/methodology used in achieving the project objectives in section four. The learning modules are then discussed with specific hardware/software being introduced during each relevant learning module in section five

Foundation Fieldbus Interoperability Testing On Project

Since Fieldbus was introduced in 1980s, leading process control suppliers started to implement their own proprietary protocols and none of them could talk together. The Foundation Fieldbus was implemented in 1994 to achieve an internationally fieldbus standard. A test need to be conducted to proved the interoperability of Foundation Fieldbus. This report will discuss about the Fieldbus and the work that done during the Foundation Fieldbus Interoperability Testing. The main objective of this project is to perform technical verification and interoperability of Foundation Fieldbus host and devices from various manufacturers. For the industry to adapt to the Fieldbus system, a comprehensive understanding on the operability of the system is required. This project aims to provide a familiarization to the Fieldbus system for scientific researchers and engineers for further development intended for laboratory or industrial application and testing. The laboratory testing will cover three main tests which are basic interoperability test, stress test and diagnostics capability test. For the first phase, the test is focused on basic test. The test will be conduct using the Yokogawa Centum CS3000 system as hosts. The outcome of this test will be implemented in PETRONAS Groupwide in the form of guidelines, procedures and standards on Foundation Fieldbus

Remote experimentation network - yielding an inter-university peer-to-peer e-service

The goal of this paper is to discuss the benefits and challenges of yielding an inter-continental network of remote laboratories supported and used by both European and Latin American Institutions of Higher Education. Since remote experimentation, understood as the ability to carry out real-world experiments through a simple web browser, is already a proven solution for the educational community as a supplement to on-site practical lab work (and in some cases, namely for distance learning courses, a replacement to that work), the purpose is not to discuss its technical, pedagogical, or economical strengths, but rather to raise and try to answer some questions about the underlying benefits and challenges of establishing a peer-to-peer network of remote labs. Ultimately, we regard such a network as a constructive mechanism to help students gain the working and social skills often valued by multinational/global companies, while also providing awareness of local cultural aspects

Commissioning and implementing a PROFIBUS network in the Universal Water System

The Universal Water System (UWS) was built for instrumentation and control engineering students to design, implement and test different control schemes. The system has been primarily developed and designed by fourth year undergraduate and master’s students with the help of on-site technicians and electricians for installation of high voltage wiring, hardware equipment and IT related tasks. As the UWS is a learning tool that provides hands on experience with an industrial grade environment and equipment, improvement and maintenance of its functionality is a vital part of the on-going thesis projects. The main objectives of this work are split into three major segments. The first was commissioning the UWS, which consisted of updating the system’s software, replacing faulty equipment and ensuring appropriate functionality of the plant’s hardware. Two PROFIBUS Decentralised Peripherals (DP) flowmeters had been purchased to replace two faulty positive displacement flowmeters in the system. Hence the second objective was implement a PROFIBUS DP communication network for the new devices. The last objective was to design, implement and test more advanced control schemes through Open Platform Communication for the newly upgraded plant. With the project now complete, the UWS is operational with a fully functioning PROFIBUS DP communication network. The server computer’s operating system has been upgraded, while the Compact RIO’s firmware and the programming software has been updated to the latest version. Faulty equipment has been replaced and commissioned. Namely, two replacement flowmeters and an electric flow valve. A PROFIBUS DP network has been implemented to communicate with the two replacement flowmeters. An unexpected technical difficultly led to 5 variable speed drives being added to the PROFIBUS DP network. Additionally, the compact RIO’s code has been redesigned to improve efficiency, provide cyber-security, and to reduce the complexity of the client program. Due to unforeseen circumstances and time constraints the time taken to commission the plant and implement PROFIBUS was far greater than expected; two of the three project objectives were completed, pushing the advanced control schemes and Open Platform Communication to future work. Overall, the main accomplishment of this thesis besides the project objectives, is that the system has been updated, refitted and ready for operation for the next thesis student; so they do not run into the tedious and painful issues found during this project
